Error with ApplyOrbit operator with ERS/Envisat SLC from ESAR On-The-Fly System

Microwave Toolbox
#1

Hi all,

Recently I got some Envisat SLC data from the ESA On-The-Fly (OTF) system (https://esar-ds.eo.esa.int/oads/access/ ) but I am getting errors while trying to apply the ApplyOrbits operator. I got the following error message (after the latest updates):

user:/media/sf_SAR# org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V
org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V
org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V
org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V
org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V
org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V

Same error with ERS SAR SLC from the ESA OTF system.

Can anybody help me? @marpet, @lveci, @jun_lu, @mengdahl

I even have the orbit files locally, but even if I change the settings from the file /home/user/snap/etc/snap.auxdata.properties on the line: OrbitFiles.delftEnvisatOrbitPath = /media/sf_Rome_SAR/orbits/Envisat , the result does not vary

I assumed that SNAP always provided backward compatibility, but maybe this error could even be caused by some new metadata (or a different one) on the new SLC focused by ESA.

Has anybody faced the same issue?

Let me know!
Thanks in advance

I downloaded the ASAR and ERS products and ran apply orbit with DORIS and PRARE orbits. SNAP downloaded and applied them fine on Windows 10.

I suspect you may be using Linux and the JBLAS library needs a fortran dependency installed.

try:

sudo apt install libgfortran3

Solved! Thank you so much!

Is any way this library is integrated with the SNAP version for linux?
I believe I will not be the only one getting this error.
Best regards
